Design and practice of geochemical data processing and analysis software
In order to strengthen international geoscientific cooperation between China and other countries,promote China's software technologies and methods with independent intellectual property rights,and support the construction of a new type of world-class geological survey bureau,this paper used modern computer technology,geographic information technology,spatial database technology,and multivariate statistical analysis method and developed an international software for geological survey data processing and analysis system(GeoExpl)by using component object model(COM)technology and the ArcGIS Engine application programming interface(API)of the Environmental Systems Research Institute(ESRI)as the development framework for geospatial analysis and processing.In addition,C and C++were employed as the development languages for each function of the software,and a process system of survey and geochemical business processing was set up,which integrated geochemical data processing,data analysis,data management,and production of geochemical multi-type thematic maps.The data integration management of analysis data,processing data,graphic data,and cartographic results was realized by taking the workspace as the management unit creatively.Through the research and development of GeoExpl,the integration of the whole process from geochemical data processing to result sharing was realized,breaking the previous monopoly of foreign software in terms of technology and realizing the integration of various types of methods and innovative algorithm research and development for geochemical data processing and analysis.The software has received positive feedback from its application in a number of projects and countries,proving that the technology of the software meets the needs of international cooperation.
